There's no ZPH in Tarantula

[S.gage]

I assumed that the Hollander was supposed to originally be named the Blitzkrieg, but was changed either because the writer decided it wasn't fast enough, or someone higher up felt it had unfortunate implications (which if that was the case would mean someone changed their mind by tro 3060).

I mean, "Dutch Guy" doesn't seem like a particularly imposing name...

I thought something like this, too. Specifically, since both were introduced by Coventry Metal Works, I thought maybe one engineering team had drawn up early designs schematics (no prototype, no testtype, etc.) of the the Blitzkrieg. When they introduced the concept, the company executives insisted on a smaller, slower, cheaper proof-of-principle design, which became the Hollander.

Some mechs have designations that don't match their English names.  TRO 3055 was a particularly serious offender in this regard, in addition to the Trantula there's the PPR-5S Salamander, the BZK-F3 Hollander (this one, at least, is because BZK is for bazooka, IIRC), the MR-V2 Cerberus, MDG-1A Rakshasa, ALM-7D Fireball...

My head canon also has a pair of explanations for the MDG-1A Rakshasa, either:
A, There was a mis-translation, and the engineering team thought the Mad Cat was called a Mad Dog by the Clans, (more likely in my mind) or
B, The design actually started by trying to emulate the Vulture, but the combination of trying to find mass for pulse lasers and the added mass of Inner Sphere LRMs forced the increase in mass and changing the loadout's lasers (in the same manner as the Black Hawk-KU). After the changes were made, the design resembled the Mad Cat more than the Vulture, so they added the torso pulse laser in homage to the Mad Cat.
